Or this Holmes fan can be mounted in reverse in your window to exhaust stale indoor air. This twin window fan is designed to fit into most slider and double-hung windows.

However you must know the need for your room for this device is mostly appropriate for moderate airflow needs not heavy airflow needs. Another thing to note you need to consider the size for your window before making the choice.
